Abstract: A tape cassette dust door latch, a dust door latch spring assembly and a related method for assembling the dust door latch into the tape cassette. The dust door latch has a lock plate with a boss projecting perpendicularly therefrom and a coil spring with first and second ends, the first end of the spring surrounding the boss and the second end of the spring being a free end. The cassette has an upper half case and a lower half case, the upper half case having an abutment member located in the vicinity of the lock plate, and the lower half case having a means for rotatably receiving the dust door latch. In the method of assembling, first, the dust door latch is inserted into the receiving means in the lower half case, and then the upper half case is assembled onto the lower half case such that the abutment member receives the free end of the coil spring, directs it downwardly, and holds the coil spring in a biased position. This dust door latch, dust door latch spring assembly and the method for assembling the dust door latch into the tape cassette provide more efficient production and automated assembly of tape cassettes.

Abstract: In apparatus for optically coupling optical fibres, each optical fibre fits into and is supported by an expanded-beam type optical component (46, 48) that is optically structured to collimate the output from an optical fibre when the fibre is located at the focus of the optical component. The optical components fit into a housing (40) in such a manner that the optical components are aimed in different directions. The housing includes optical means (50.52), including a holographic layer (52), positioned within the housing to intercept the output from one optical component (46) and precisely direct it into the other optical component (48) and vice versa. The holographic layer is initially interferometicallyformed, by exposure to radiation directed through the fibre in the optical component, with variations of index of refraction. The use of the holographic layer in the optical path permits the tolerances related to the angular tilt of the lens surfaces of such optical components to be greatly relaxed. More than two optical fibres can be coupled in predetermined combinations using two or more holographic layers (Figure 10).

Abstract: An instrument for obtaining quantitative, three-dimensional and tomographic information relating to x-ray and gamma-ray emitting objects and for the orthoscopic viewing of such objects includes a multiple-pinhole aperture plate (22) held spaced from an x-ray or gamma-ray to visible-light converter (24) which is coupled to a visible-light image intensifier (26). The spacing between the aperture plate and the converter is chosen such that the mini-images of an emitting object formed by the pinholes do not substantially overlap as they impinge on the converter. The output of the image intensifier is digitized by a digitizing camera (36) in terms of position and intensity and fed into a digital computer (40,42). The computer may output quantitative information relating to the emitting object directly, such as that relating to tomograms, or provide information in analogue form when coupled with a suitable viewing device (52,54), to give an orthoscopic, three-dimensional image of the object.

Abstract: The longitudinal position of an inner barrel within a core barrel assembly (10) can be adjusted and locked in the field without necessitating the disassembly of the cartridge cap assembly (34) within the core barrel tool (10), and therefore without entailing loss of expensive rig time. The inner tube (72) is coupled through a swivel assembly (52) to a cartridge cap (34). The cartridge cap (34) is threadedly coupled to the coring tool (10), and in particular to the outer tube (16). Thus, the cartridge cap (34) is arranged and configured to be rotated, and thus longitudinally adjusted with respect to the outer tube (16). An upper portion of the cartridge cap (34) is provided with a plurality of radially expanding fingers (50). A jam nut (48) is disposed within a cylindrical array formed by the fingers (50), and is threadably engaged with the inside surface of the fingers (50). The jam nut (48) has a frustoconical shape, and thus as the jam nut (48) is advanced longitudinally with respekt to the fingers (50), the fingers (50) are urgend outwardly, ultimately in a tight and locking contact with an interior surface of the coring tool (10). A hollow cylindrical wrench (102) is disposed throught the end of the core barrel (12) to engage the cartridge cap (34) and rotate it to the desired longitudinal position. A jam nut wrench (110) is disposed through the hollow cartridge cap wrench (102), and when the inner tube (72) has been appropriately adjusted is used to advance the jam nut (48) downwardly in the fingers (50) to expand the fingers (50) and thus lock the longitudinal position of the cartridge cap (34).

Abstract: A device is provided, associated with the accelerator pedal of motor cars adapted to cause the lighting of the brake lights shortly before the brake pedal is applied in case of braking in an emergency. In one disclosed version of the device, it comprises a bellows mounted on the accelerator pedal. During normal driving, the bellows is pressed down to minimum volume thereof. When abruptly released, a sub-pressure is developed which is used to momentarily lift a metal flap which closes the brakelights circuit. The lights remain on until the light circuit is taken over by the brake pedal switching circuit. According to another version, the operation is based on the relative abrupt movement of a magnetic core surrounded by an induction coil. The electromotive force will generate a current effective to close the brakelights circuit.

Abstract: The subject of this invention is the design of a mechanism for the feed of the paper in a flat plotter for drawing, which is cheap and has a high level of operational reliability. 
     The mechanism consists of a reduction motor which rolls up the paper after it has passed through the drawing zone; in the drawing head an optical line reader is fitted which is designed to read a trace made by the drawing tool once the drawing has been completed in one window; when this trace is detected, a stop command is delivered to the rolling- reducer motor. Once the paper feed has stopped, in order to exactly join and continue the drawing of the following window in the correct form, the drawing tool carries out a search forthe trace at very low speed. When the line has been detected in this process, the plotter continues with the drawing operation in the correct place.
